$ ls -a
Shows you all files, even files that are hidden (these files begin with a dot "."). Those hidden files are normally system files.
And the double dot (..) indicates the parent directory.
/home/oracle $ pwd
/home/oracle
/home/oracle $ cd ..
/home $ pwd
/home

The single dot represent the current directory, and double dot directory is the upper current directory.

Hi
. - present working directory/current working directory - the directory in which the user is at present
.. - one directory before the current directory
ls -a - listing of hidden files in the current directory.Hidden files start with '.'prefix like .xauthority.
ls command doesn't list those files.So we can use ls -a command instead.
